Well after months of construction I finally unboxed my EP350 and noticed that I the back control plate is identical to that of the EP500!

I didn't know anything was out of the ordinary because I had gone through the user guide packaged with my 350 and the diagram of the back controls were all listed.

It was only when I went to look up the user guide for the 350 on Axiom's site did I notice that it doesn't have the USB port and Trim knob listed!

In looking at the user guide for the EP500, I noticed that the diagram of controls is identical to what is installed on my EP350!

Now I've discovered this thread, but I'm at work so I cannot pull the grill to check the driver or view the included user guide to make sure it says EP350, but it looks as though I was able to obtain an update/hybrid EP350 from the Factory Outlet Store!

When Axiom had their anniversary/picnic we saw some test models of the ep350.
Upon asking they were testing to see if it was worth while financially to have the same components in all subs and if there was a benefit in sound/performance.
